Question 9 Over time, the proton-proton chain and other fusion processes generate large amounts of helium inside stars. The conditions within some stars causes this helium to fuse. This is known as the triple-alpha process. Can you predict the product for the first step, shown below? He + He - A. Helium-4 B. Beryllium-8 C. Carbon-12 D. Oxygen-15 a A B Oc C O d D
